ABSTRACT:
An improvement in distributors for air-laid fibers wherein one or more impellers within a distributor housing receive fibers from a hammer mill or other source, and impel fibers smaller than a certain size through a first screen extending over the outlet opening of the distributor housing onto a moving forming wire. A partial vacuum is formed beneath the forming wire to hold the fibers thereon and to form a continuous web of fibrous material. The impellers are blades which rotate about a vertical shaft immediately above the first screen. The invention is directed to improvements in the first screen, wherein it is endless and is mounted for movement across the outlet opening of the distributor housing, in the same direction and at the same speed as the forming wire.
